,This invention appertainSQIt' pen andp more particularly to an anti-loss attbfhffil'e'ht therefore. Fount'ai I I universally provided with some type of springclip for engagement with the pocket of the owner to hold the same in place. In actual practice, the pens and pencils have a tendency to gradually ride out of the pocket and if the wearer bends over, there is a likelihood of the pen or pencil falling out of the pocket; resulting in the loss or damage thereof. This is particularly disastrous with the costly pen and pencil sets now found on the market at the present time.

It is, therefore, one of the salient objects of my invention to provide an inconspicuous attachment for'the clips or writing implements, which will automatically increase the tension of the spring clip on the pocket, if there is any tendency of the implement riding out of the pocket, thereby preventing the accidental loss of such implement.

npens I and ieal 3 Figure ,3 is aide the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding partsthroughout the several views the letter A generally indicates my attachment for the resilient clip C of a fountain pen F.

The fountain pen F can be of any preferred character or make and includes the barrel 5 and the removable cap 6.

The resilient clip C can also be of any prefer-re character and is anchored to the cap 6 in any desired way. The resilient arm I of the clip ex- Another primary object of my invention is to provide such an attachment which can be readily and naturally held in an inoperative position by the user during the intentional withdrawal of the implement from the pocket.

A further object of my invention is to provide an anti-loss attachment for the clips of writing implements embodying a cam pivotally carried by the lower free end of the clip for engagement with the pocket, adapted to automatically roll toward its high point upon the working out of the implement from, the pocket for increasing the tension and the holding qualities of the clip upon I the pocket, the cam arrangement being such that the greater the upward pull on the pens, the tighter the gripping of the cam upon the pocket.

A still further object of my invention is to provide a tooth on the extreme high point of the cam for insertion in the fabric of thepocket. so as to positively preclude the slipping of writing implements from the pocket should the cam ride to the extreme high point on the pocket.

With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be tends along the capG and preferably terminates in a hollow head 8.

My anti-loss attachmentA includes a cam or eccentric9 and the same'is mounted in the head 8 for rocking movement. A pivot pin ill is carried by the head and supports the cam for turning movement. The cam normally projects slightly beyond the inner edge of the head and spring arm and the extremely high point thereof can be provided with a tooth I I. The tooth can be omitted,

, if the use thereof is found unnecessary.

The outer face of the cam can be provided with a stop shoulder l2 which 'is adapted to engage the head 8 when the high point of the cam is swung outward so asv to prevent the high the cam on the pivot pin. The outer arcuate wall hereinafter more specifically described, claimed, I

and illustrated in the accompanying drawing, in-

clip being shown broken away and in section to illustrate structural detail, the pen being shown inserted in a pocket of a garment.

M of the head 8 substantially hides the cam from view of the casual observer. Hence the cam does not detract from the appearance of the pen or clip.

In use of my attachment, the pen is slipped in the pocket in the ordinary way with the clip against the outer surface of the pocket. As the pen is pushed down in the pocket the cam is normally swung back against the arm I of the clip to an inoperative position, as i clearly shown in Figure 1 of the drawing.

To remove the pen from the pocket, it is merely necessary to insert the finger under the free end of the clip against the cam and hold the cam against rolling movement. The pen can now be pulled from the pocket and the cam will still "greater the pull on tension of the clip.

to ride from the pocket, the upward movement of the clip and the ride of the cam on the pocket will swing the cam towards its high point. This will automatically increase the tension of the arm of the clip and consequently the pen will be held tight in the pocket. Obviously, the greater the pull on the pen the further the cam will roll towards its high point and consequently the the pen the greater the Where the tooth Iris used andthe cam r0115 to its extreme high point the tooth will ride into J the fabric of the pocket and further prevent the accidental withdrawal of the pen. The shoulder l2 prevents the too far rolling of the cam as previously described. w

While I have illustrated a pen in the drawing and described a pen in the specification, it is to be understood that my attachmentcan-be used with resilient clips for any purpose, such as pencils, combs, rulers, etc. I Changes in details may be made without departing from the spirit or the scope of ,my invention but what I claim as new is: jf I The combination with a bodyihaving a spring 4' clip with its lower free end normally urged toward said body, a hollow head on the lower end of said clip, of an anti-loss attachment for the body including a cam pivotally mounted for turning movement in said hollow head and having its outer edge protruding beyond the inner face of the clip and head at all times and projecting toward said body, and a shoulder on said cam for engaging said head to limit the outward swinging movement of the'cam. a
